Figure 6. REE discriminant diagrams for zircons. a - Y vs U in ppm and b -Y in ppm vs Yb/Gd jointly characterise the type of granitoid as a granodiorite and tonalite after [3] where 1 = Aplites leucogranite, 2 = granites and 3 = granodiorites and tonalites. c - U vs Th in ppm. d - Ce/Sm vs Yb/Gd chracterise the source of the granitoid as crustal after [42]
